【 摘 要 】

We predict heating of quasiparticles driven by order parameter oscillations in the resistive state of short superconducting microbridges. The finite relaxation time of the magnitude of the order parameter vertical bar Delta vertical bar and the dependence of the spectral functions both on vertical bar Delta vertical bar and the supervelocity Q are the origin of this effect. Our results are opposite to those of Aslamazov and Larkin [Zh. Eks. Teor. Fiz. 70, 1340 (1976)] and Schmid et al. [Phys. Rev. B 21 5076 (1980)] where cooling of quasiparticles was found.
